linux opencv 安装和配置

悠悠 2022-06-12 07:57 254阅读 0赞

在fedora16 和 CentOS 下面配置OpenCV，由于不同主机装的软件的都不一样，所以不能一概而论

大概需要的开发套件：

pkgconfig  libpng  zlib libjpeg  libtiff libjasper

ffmepeg GTK+ 的基本库(这里可选，用到的时候再装也行)

下面是我的主机安装配置OpenCV。

# opencv 下载 #

[http://sourceforge.net/projects/opencvlibrary/files/opencv-unix/2.2/][http_sourceforge.net_projects_opencvlibrary_files_opencv-unix_2.2]

在centos和fedora16下面，一般都把用户的软件装在 /usr/local/xxx 下面

$ cp OpenCV-2.4.0.tar.bz2 /usr/local/
    
    $ tar -xvf OpenCV-2.4.0.tar.bz2
    
    $ cd  OpenCV-2.4.0
    
    2.4.0的下面是以CMakeLists.txt形式
    
    $ yum install cmake
    
    $ cmake CMakeLists.txt
    
    $ make && make install

OpenCV 会安装在 /usr/local/lib 目录和 /usr/local/include/opencv/

### 环境变量配置 ###

$ vim /etc/ld.so.conf

最后一行加入 /usr/local/lib

$ ldconfig

或者

export LD\_LIBRARY\_PATH=/usr/local/lib

### OpenCV测试 ###
